Iaieh of the lugs 29 is hugs 2U are mounted-"commi-ted it its bottoni with u rod 33 und the two rods 33 are eachprovided at the inner ond with a slot 32, the. slots being l l l l l l:it--llieir omer edges are enoh provided with n l l a i adapted toregbter with each other. Pivot of these lugs is a screw A49 providedwith a rcvolublcI nut 50, the latter being sandwiched fas vopposit-elydisposer 4porotos is placed in such position that the 'tity of glassrequired will he severed. rlho lpins 33 are mounted in heads 84, the'latter 1 `closed. -Moreoven the floors`will be efl'ecteing secured inposition by bolts 35 and thumb nuts 36. 'lwo levers 37, of substantiallyarcuate forni, are crossed and pivoted upon a pin 3S. Each lever 37 isprovided with a pin 39 and alsol with au arcuate slot 4t). Each arcuateslot 4() receives a. pin 41, the latter being mounted upon ascmicircular door 42. 'lhe two doors 12 are mounted upon pivot' pins 43,and are provided with levers- 44 havingl weights 45 adjustably mountedthcreupim, The weights are preferably so adjusted as to keep the doors42 luirmally closed.

A c vlinder 31 is provided '.vitl. an extension 31 in alinementtherewith, as will be understood from Fig. 4. llncirciing the' c vlindrical extension 31l is a cup 43 to which the semicircular doors 42are secured b v the pivots 43. The cup 46 is provided with two slots 47,and adjacent to each slot is a lug 4S. Journaled to each between lugs 51which are integral with the cylindrical extension 314% By turning thetwo nuts 50, the cup 4G is-raised or lowered relatively to thecylindrical extension 31%- and hence the internal capacity or volumeircumscribed is varied at will. i

A pointer 52 is rigidly mounted'upon ,the Cup 46 and travels over agraduated scale 53 whenever the cup 46 is raised or lowered. By simplyturning the nuts 5U and watching the pointer 52 and scale 53, theoperator is enabled to adjust the device so as to cut any predetermineda-.nount of glass.

It will be noted that the heads 34 may, b v aid of the slots 3o, beadjusted vertically in relation to the lugs 2f), and that by thisadjustment the virtual length of the rods 33 may be increased ordiminished. llcnce, the limit of trnvcl of the levers 37 may becurtailed, so that the doors 42, while always adapted to close the lowerend of the cup 4o, may not recedeI very far from each other when they.swing apart. ln other words, the operator, by adjusting the bolts 35vertically in relation to the slots through which they mss, can controlthe degree of owning allowed for the doors 42. lt will e further notedthat whenever the blades 22 are reciprocated in o )posite directions,the lugs 2l) cause the rods 33 to rock the levers 37 and thus open andclose the semi( ircular doors 42.

(lur invention is used as follows: 'lhc apdoors` 42 are directly over aglass press mold which is to receive the glass. 'lho cup 46 is nowadjusted b v aid ol' the gage above. dcscribcdso that. the proper volumeor quanarts being in their normal condition, the lades '2 will be swungapart, as indicated ivcly locked, owing to the pressure upon the pins41":by the levers 37 (see Fig. 3,). The cylinder; 31, `with itsextension 31a and cup 4 6, together now constitute a receptacle. 70(llass'is now run into this receptacle, the upper end ol' the cylinder31 being enlarged ory madcin t-he form of a hopper to facilitatc thispurpose. 'lhc upper level of the glass may be anywhere between the upperend of f1.5 the cylinder 3 1 and the blades 22. The operator now pullsupon the cord 13, for instance by aidot a t-readle, or even by hand. 1 Y'l`l.:`scaoses the cam 11 to dccend. The.cy lindriea-l'portions 15 ofthe lovers 17 now 80 move. outwardly, as will be understood from .1"ig.6, and the cutting surfaces 24, 25 of the. shearing blades a proach. andpass each other, so as to ma 'e a shearing cut.- 'lhe slots 32 'allowthe rods 33l to move far enough A85 to make this cut without disturbingthe positions ol the. doors After the 'cutting edges pass cach other, orin other words, after the shearing cut is made, however, the rods 33continue to engage the pins 39 and 90 rock the levers 37. In doing this,downward pressure is exerted upon the pins 41 and the doors 42 arethereby opened and the severed v,glass is thus ejected, The. pull uponthe cord 13 now being relaxed, the spring 14 95 raises the cani 11 toits normal position, and the levers 17, thtl shear blades, and all othermovableparts immediately connected therewith resume their respective.normal positions. '.lhis leaves the doors 42 closed and 100 locked, andthe shear blades 22 move 'a art ready to operate upon a new charge of gass. VWe lind that. the apparatus is very positive and reliable in itsaction, which is praciically continuous. A

it will be noted that the doors 42 do not begin to open until after thecut is entirely finished, and then these doors open abruptly to airedetermined degree, controllable at the will of the operator.
